R/W characteristics means the function is with read and write characteristics. For example,
"communication control command" is writing chrematistics and control the VFD with writing
command (06H). R characteristic can only read other than write and W characteristic can only
write other than read.
Note:
when operating on the VFD with the table above, it is necessary to enable some
parameters. For example, the operation of running and stopping, it is necessary to set P00.01
to communication running command channel and set P00.02 to Modbus communication
channel. And when operate on "PID reference", it is necessary to set P09.00 to "Modbus
communication setting".

Goodrive20-UL Vector VFD
Note:
The code consists of 16 bits which is high 8 bits and low 8 bits. High 8 bits mean the
motor type series and low 8 bits mean the derived motor types of the series. For example,
0110H means Goodrive20-UL vector VFDs.
7.4.3 Fieldbus scale
The communication data is expressed by hex in actual application and there is no radix point
in hex. For example, 50.12Hz cannot be expressed by hex so 50.12 can be magnified by 100
times into 5012, so hex 1394H can be used to express 50.12.
A non-integer can be timed by a multiple to get an integer and the integer can be called
fieldbus ratio values.
The fieldbus ratio values are referred to the radix point of the setting range or default value in
the function parameter list. If there are figures behind the radix point (n=1), then the fieldbus
ratio value m is 10
n
